To all whom it may concern: r

v w J. WIBWALL, a citizen 'of the United States, residing at Portland,in the county of Multnomah and State of Oregon, have invented a new anduseful Improvement in. Manifolding De-- vices, of which the following isa specification, reference being had to the accompany-- in drawings. yinvention relates to a class of devices wherein carbon sheets of commontype are used in manifolding copies.

The object ofmy invention is to provide a device wherein continuouspaper strips in series maybe supplied from a container and carbon stripsbetween the original and the copy strips of the paper in likecontinuous.

manner. The objects, as well as other advantages, I accomplish by'theconstruction, combination and arrangement of parts illustrated in theaccompanying drawings which form a part hereo Figure I is a sideelevation of the device,

A case 7 of desired form and with a cover is provided. Within the case aseries .0 supports 8 are secured. A series of tra s 9 are deposited uponsaid sup orts. T e trays receive pape strips lO continuous materialwhich may be transversely perforated to facilitate itsdivision intodesired parts.

upon theroller is in rotatable'position in the bear ng 13 and is rigidin the rotatable bearing 14. A gear train 18 is rigidly secured withoutthe case wall upon the thimble bearings 14 and has in connectiontherewith an idler 19 to arran e a rotation of the rollers in the sameirection. Below the rollers 11 is a guide roller 20 arranged in relationto the lowest tray 9 and paper 10 therein. A gear 21 is pivotallymounted upon the outer case wall in position to engage the two uppermostgears of the train 18 and rotate them in the same direction. The gear 21has an operating handle 22. Uponthe outer wall of the case a lever 23 ispivotally mounted. Upon one end it has a' pivoted tension roller 24arranged in av manner whereby the roller will engage the lowest gear ofthe train 18 and prevent the rotation of the train members when thepinion is raised into such engagement-by means of the lever and the gear21 is not rotated.

A spring 25 is formed and secured opposite the roller 24 in a manner toretain the roller in engagement with the gear member and to retain itout of engagement as the roller is either raised or lowered in travelingengagement with the spring 25. Carbon strips 26 of common type areplaced upon the rollers 11. The forward part of the case is proxvidedwith a writing table 27. and below it a container 28. A guide roller 29is pivotally mounted at each end in the "free ends of oscillating arms30. Springs 31are secured to the arms and case in position tocause thearms to depress the roller 29.

In the forward part of the container 28 a transverse roller 32 ispivotally mounted in bearings 33 which are provided with sprin 34 topress the roller bearings upward y in their sockets. A sprocket 35 isrigidly keyed on the end of the roller 32 and opposing this sprocket asecond sprocket 35 is pivotallf mounted on a pin secured to the outerwalof the case opposite the one with the gears .18.

Above the chain a longitudinal slotted guide 37 is rigidly secured alongthe container and forward partof the case. Within the guide a grooved,slidable carrier 38 is placed. In thecarrier 38 a vertically movable pin39 is positioned with a spring 40 to press it upwardl the pin beingretained in the carrier y a collar 39' and also having its'lower pointedend over the A" continuous chain 36 extends, about 'the sprockets 35-45.

upper path of travel of the chain 36; A. tension spring 41 is secured atone end to the carrier 38 and its opposing end is secured to thecasenearits rear end. In the forward part of the container is a guide roller 42pivotally mounted above the roller 32,: A second guide roller 43 ispivotally mounted in bearings 44 slidable in sockets and provided with srings 45 to press the bearing rearwar'dly. deans 46 are provided tosecure and retain the hinged bottom of the container 28 in position uponthe container. A paper guide 47 is secured to the lower surface of thetable 27. g

It will now be seen that when tablets or bloclrs of lolded continuouspaper strips are placed in the trays 9 and these on the supports 8 asshown in Fig. H, the rearupper ends of the strips in the upper trays aredrawn forwardly over the opposing rollers ll and the strip in the lowesttray below the roller and thence outwardly beneath the guide roller 30,over the table 27 The bottom of the container having been removed, thestrips of paper are drawn over the roller 42 and threaded between it andthe roller 32. The bottom strip is then separated and all of the upperstrips drawn downward and. threaded between the rollers 32 and 43, whilethe bottom strip is allowed at the same time to project a desireddistance into the con tainer, the other strips projecting outwardlytherefrom. While the paper strips are be ing drawn first over the table,the friction roller 24 is released from the gear train and the carbonstrip rollers are rotated to pass carbon strips between the paper,strips a "desired distance, and the friction roller 24 again broughtinto engagement withthe gear 1 train to prevent the carbon strips fromfeeding farther outwardly. It is tofbe noted that the carbon strips inmy device are passedbetween the sheets outwardly in a longitudinaldirection, which differs from other devices, which usually place thecarbo strips front a direction. When the carbon strips are worn in oneplace the r stop released and carbon strips d m var y a desireddistance, as

'- out, to supply rbon strips locked con strips pass out of thecontainer 31', When section of s has been inanioutwardly to the e d "'eon .a manner to allo paper St hea set paper until it makes another told,aided therein by the guiding spring 47. I is desired to cut the carbonstrips adjacent to'the guide roller 29, then the pin 39 is a plied atthe rearward end of the guide to t e chain 36 and the chain drawnforwardly, which causes the roller 32 to rotate forwardly and the paperstrips to be passed above it and released from the roller mechanism. lhestrips may then be raised and the carbon strips cut as desired. Thepaper strips are then threaded again in the rollers with new carbonstrips between theinv as before described. I contend that the use oftrays differs radically from the use of rollers to supply the paperstrips, as the mechanism may draw the paper strips simultaneously anevenly, without friction or the necessity for greater power to do so.The object of the container is to supply a means for retaining onemanifold copy as a secret record a series of trays in the casepositioned one above the other and arranged to contain continuous stripsof paper folded in zigzag pad form, and rollers in the outward part ofthe container arranged in a manner to al- 'low the paper strips, oneabove the other,

as drawn from the said trays outwardly over the table, to be threadedthrough the rollers and when these are rotated to allow the upper stripsof the paper to be passed outwardly and the lowest strip to be passedinto the container in folded term, for the purpose inicated.
